To aZZ whom it may concern.-

Be it knowr that l, THEoHILLtrEc, asubject of the King of Prussia, German Emperor, end a resident of Bucharest, in the Kingdom ofRoumania, have invented certain new and useful Arrangements for Messuring vQuantitic-zs of Liquid, of which the following is a specification.

The invention relates to improvein nts in devices or arrangements for measuri g the quantities of liquids or the like.

Arrangements are known inlwhich the measuring is efiected by a mano neter united by a column of air or gas with the reservoir containing the liquid tobe mous ured. in these known devices there is theinconvenience that the column of air or gas ,rvhich is between the manometer and'tb/ereservoir is influenced by the pressure of the column of water, because during a greater height of the column of water the air before the manometer-plate is compressed, and vice versa. in these devices it is not'pos sible to keep the same relations during a different time.

Under the present invention the liquid to be measured is caused to act directly on the membrane or spring of'the manometer and the said spring or membraneis arranged at such a level as to be above the base of the said reservoir. in this way the zero-point is obtained for measuring at a constant level above the base of the reservoir and is not allected by irregularities in the form of the base.

In the accompanying drawings, which illustrate the invention, Figure l is a longi' tudinal elevation, partly in section, showing the device with the vessel for receiving the liquid to be measured. Fig, 2 is a side elevation, and Fig. 3 a plan thereof.

As shown in the said drawings, the reservoir 1 serves to receive the liquid to be measured. 0n the top of said reservoir is secured, by ip'eans of the flange 2, a cylindrical vessel open at the top, which has a branch pipe t leading oil per endicular thereto about halfway between t 1e top and the bottom of said vessel 3. Connected to said branch pipe 4 is a union-piece 5,-joined to the manometer 6. The manometer 6 may be provided with any suitable mechanism for the present apparatus and may either vertical. or horizontal.

In the term shown a membrane-manometor 1s rovided arranged in a vertical posi- 'tion, $11 which the liquid-pressure acts di- Specification of Letters Patent. Anplicatiou filed December 10, 1904. Burial Ho. 238.351.

rectly on the membrane 7 and is transmitted to the rod 8, actuating the indicator-spindle. "When the manometer-scale is marked to indicate kilograms or grams, it gives the weight of the column of liquid per unit area-4502' instance, for one square centimeter of surface of the reservoir k-so that the weight of the liquid can be read ol'l' directly on the manometer. Obviously the scale of the manometer can be arranged for any other system of weights.

The vessel 3 is provided with. a sand-tra 9 and with a cook 10, and the latter is provh ed rith elead seal 11 to provide security against unsutl'iorized opening. Preferably the rip-- pcr end 13 of the vessel 3 projects above the level of the'base of the reservoir 1, so as to prevent the entry er scum and particlesof It is referable to have such dimensions for the ranch 13 that its u per edge is in alinement with the upper en of the spring of the manometer, so that the zero-point of the manometer-membrane is the zero-point of the branch 13, and on running off the liquid from the cock 10 the liquid-level iii the reservoir can never be be low zero. it is evident that before the reservoir 1 is iilledwith li uid the fillihg of the reservoir so made It at the liquid imthe branch 4 directly contacts the membrane 7. The filling can be effected by a screw-pin 12. which can be unscrewed during filling and rescrewed after filling.

It is obvious that the shapes of the vessel 1 and the vessel 3 are immaterial as regards the essence of the invention. The reservoir shape. The )rescrit arrangement may also be employed in stationary basins for measuring liquid therein without departing from the spirit of the present invention.

Having thus described my 'iuv'entichg, what I claim as new, and desire to secure y Letters Patent, is- 1 r The combination, a n1casuring-reservoir, having an outlet-tube, the inner end of said tube. being above the bottom of said reservoir a manometer, having a spring-plate,- said plate being on a level with the inner end of said outlet-tube and a. branch tube, connecting said outlet-tube and said manometer. .ln testimony whereof l-have hereunto set ,my hand in the presence of two witnesses.
